[OPGELOST] "draadloos netwerk is uitgezet"?

[canti]

Ik zag toevallig bij het aanklikken van het netwerk-icoon dat draadloos netwerk uitgezet is. Ik kan het niet aanzetten, ook niet met het rechtsklikken op het icoon, daar is de optie "draadloos netwerk aanzetten" uitgeschakeld. Hoe kan ik het aanzetten? Thuis internet ik bedraad, maar ik zou in de Koninklijke Bibliotheek graag gebruik willen maken van het draadloos netwerk. Mijn laptop heeft zeker een wifi-kaart.

Misschien moeten er nog drivers geinstalleerd worden.
Doe eens volgende in de terminal om te weten te komen welke draadloze kaart het is:

Code: [Selecteer]

lspci | grep Network

Ahja, zijt ge ook zeker dat de knop niet gewoon uitstaat?

[canti]

lspci-commando: 02:00.0 Network controller: Intel Corporation PRO/Wireless 5100 AGN [Shiloh] Network Connection

Welke knop? De optie "draadloos netwerk aanzetten" staat uitgeschakeld en de tekst ervan is in grijs gedrukt, het is dus gewoon niet aanklikbaar. Ik zie geen overzicht van verschillende netwerken in mijn buurt.

edit: enige tijd geleden was draadloos netwerk gewoon aan. Misschien ging het na bepaalde updates uit??

[Cumulus007]

Ik vraag me af of de driver überhaupt wel werkt. Je ziet dus ook geen beschikbare netwerken, omdat het draadloos uit staat? Doe het eens handmatig via de commandline: sudo iwlist wlan0 scan.

[canti]

resultaat: no scan results

Hoe zou het komen dat de driver opeens niet meer werkt? hoe kan ik het wel werkend krijgen?

[Cumulus007]

Hmm, wat vreemd. Doe eens een

Moderator edit: code-tags geplaatst

Ik heb even gekeken bij Windows (ik heb dualboot), en ik kon nog net een venstertje zien oplichten met het berichtje dat wifi gedeactiveerd is. Het heeft waarschijnlijk niet met Ubuntu te maken, is eerder hardware-probleem. Maar hoe kom ik erachter? Kan iemand trouwens iets wijzer worden van de uitkomst van lspci -v?

canti

P.S.: moderator, bedankt voor het tussen code-tags plaatsen van de uitkomst. Sorry dat ik daar niet eerder aan gedacht had...

[canti]

Ik ben een grote sukkel!! Op mijn (nieuwe) laptop is er een onduidelijk knop die het draadloos netwerk kan in- en uitschakelen. Het werkt zelfs onder Ubuntu. Nu heb ik een mooi overzicht van alle draadloos netwerken hier in de buurt (en dat is best veel).

Sorry voor mijn dommigheid...
